best coolant Ph level-??
What is the appropiate/best Ph level for BMW's coolant system?. It is my understanding this is very important for BMWs. Also, how can I test at home? Did not find anyting on ph levels in archives. Tried 3 different ways.
BTW, I use BMW blue with distilled water at all times. Been two years since changed.
TIA
